Adsorption Characteristic of Total Triterpenes in Akebia Trifoliata Pericarp by Macroporous Resin
摘要
Abstract
The adsorption characteristic of total triterpenes in Akebia Trifoliata pericarp was researched by XDA-1 macroporous resin.Adsorption dynamics and thermodynamic parameters were investigated by pseudo-first-order,pseudo-second-order model,Van't Hoff equation and adsorption isoatherms.The results showed that adsorption of total triterpenes by XDA-1 macroporous resin is pseudo-second-order kinetics equation.The adsorption isotherm is freundlich adsorption isotherm equation.Its enthalpy changes △H =-1.2792 kJ/mol,and is physical adsorption process.Gibbs free energy changes △G ＜ 0 indicated that the absorption is a spontaneous process.The entropy changes △S ＞ 0 demonstrated that the absorption process is the process of entropy increase.关键词
